摘要
Steel in subtropical monsoon regions encounters severe atmospheric corrosion. In all attempt to provide better corrosion protection, zinc-nickel alloys were electrodeposited oil steel by pulse current. Some electric variables (average current density and pulse cycle) and bath temperature oil chemical compositions and grain size of coatings were studied. Next, zinc-nickel alloys electrodeposited oil steel were prepared for atmospheric corrosion tests. In addition, the determination of the chemical compositions and the grain size of the Zn-Ni alloy coatings were conducted by scanning electron microscopy (SEM) combined with energy dispersive X-ray spectroscopy (EDS) and scanning probe atomic force microscope (AFM). Furthermore, Tafel plots were employed to evaluate the alloy corrosion behavior.
